Wildcard certificates

If you need to serve multiple subdomains with the same wildcard certificate, the best way to handle them is with a Caddyfile like this, making use of the handle directive and host matchers:

You must enable the ACME DNS challenge to have Caddy automatically manage wildcard certificates.

*.example.com {
	tls {
		dns <provider_name> [<params...>]
	}

	@foo host foo.example.com
	handle @foo {
		respond "Foo!"
	}

	@bar host bar.example.com
	handle @bar {
		respond "Bar!"
	}

	# Fallback for otherwise unhandled domains
	handle {
		abort
	}
}
